What is the correct action to take if there is a large fire on the benchtop?

In the event of a large fire on the benchtop, using a fire extinguisher is the most appropriate and effective course of action. Fire extinguishers are specifically designed to combat fires by discharging certain agents that can smother flames or cool burning materials, thereby effectively extinguishing the fire.

When dealing with fires, it’s crucial to choose the right method to minimize danger and potential damage. A fire extinguisher provides a quick and controlled way to manage a large fire, whereas a fire blanket is more suited for smaller fires or to wrap around a person whose clothing is on fire. Pouring water on certain types of fires, particularly those involving flammable liquids or reactive chemicals, can exacerbate the situation, as it can cause a fire to spread or create dangerous chemical reactions. Grabbing the nearest bag does not address the fire and can waste valuable time during a critical emergency.

Therefore, the use of a fire extinguisher serves as the best option to effectively and safely extinguish a large benchtop fire.
